quick oats
Rolled oats are oat groats that are dehusked and steamed, before being rolled into flat flakes under heavy rollers. Thick-rolled oats are large whole flakes, and thin-rolled oats are smaller, fragmented flakes. Rolled whole oats when further processed are broken down yet again into smaller flakes. This size helps them cook quicker. They can be cooked into a porridge. You can make your own quick oats from old-fashioned oats (rolled oats) by grinding them in a food processor.
oats
Oats, or Avena sativa, is a species of cereal grain grown for its seed. Oats is sold in many forms, as groats (whole), steel-cut (cut groats), rolled (flattened), crushed (quick oats) or ground into flour. Oats are a source of protein, thiamine, iron, and are a near equivalent in quality to soy protein.
Oats are often boiled and eaten as porridge, but can also be baked into savoury foods and desserts, or made into plant milk.
